performance and safety of lightforce® therapy lasers on lateral ankle sprain

Conditions: Ankle Sprain 1St Degree; Ankle Sprain 2Nd Degree; Acute Pain

Summary: djo uk ltd (enovis) is conducting this study to assess the effectiveness of lightforce® therapy lasers on pain reduction in subjects with ankle soft tissue trauma and/or sport injury. in detail this study will assess superiority of lightforce® therapy lasers combined with standard of care, represented by rice and physiotherapy/exercise program, compared to sham laser combined with standard of care (rice and physiotherapy/exercise program) on pain reduction in subjects with acute grade i - ii lateral ankle sprain. in addition, this study allows to collect post market clinical data on the safety and performance of lightforce® therapy lasers, when used, following the normal clinical practice, in accordance with its approved and ce marked intended use.

this clinical investigation is a post-market, international, multi center, prospective, randomized, sham controlled, single blind study to assess the effectiveness of lightforce® therapy lasers and to collect pmcf data on the safety and performance of lightforce® therapy lasers when used in accordance with its approved labeling, to comply with medical device regulation (eu) 2017/745 (mdr) article 61 and part b of annex xi.
